+# Tests
+
+## Running
+
+The Mosquitto test suite can be invoked using either of
+
+```
+make test
+make check
+```
+
+The tests run in series and due to the nature of some of the tests being made
+can take a while.
+
+## Parallel Tests
+
+To run the tests with some parallelism, use
+
+```
+make ptest
+```
+
+This runs up to 20 tests in parallel at once, yielding much faster overall run
+time at the expense of having up to 20 instances of Python running at once.
+This is not a particularly CPU intensive option, but does require more memory
+and may be unsuitable on e.g. a Raspberry Pi.
+
+## Dependencies
+
+The tests require Python 3 and CUnit to be installed.
